Looking at the NYC published ordinance from ATF:
Can anyone translate that from Legalese to Human?1. It shall be unlawful for any person to sell,
offer to sell or have in such person's possession
any air pistol or air rifle or similar instrument in
which the propelling force is a spring or air, ex-
cept that the sale of such instruments if accom-
panied by delivery to a point without the city, and
possession for such purpose, shall not be un-
lawful if such person shall have secured an an-
nual license from the police commissioner of the
city authorizing such sale and possession. The
sale and delivery of such instruments within the
city from one licensee to another licensee, and
the use of such instruments in connection with
an amusement licensed by the department of
consumer affairs or at rifle or pistol ranges duly
authorized by law shall not be considered a
violation of this subdivision.
Seems like you need some sort of license to sell (what about just possessing?). Does "the ban" mean that this license is never granted, or there's some other law that explicitly prohibits possession?
Any input is appreciated.
